Here we are, marching in the Intergalactic Krewe of Chewbacchus 2015.

So, New Orleans has this crazy vibe during Carnival season. On a scale between “a literal city” and “Burning Man”, it ranks somewhere around “the square root of WTF”, with parades running first on weekends, then increasing to every day as Mardi Gras approaches. So naturally, I figured the best way to experience this would be to dive right in. When I heard that the Kaiju Flambeaux Corps was looking for people to march in radio-synchronised LED suits, I jumped at the chance.

A good portion of any lit costume like this is finding a garment to use. Our parameters were something relatively-translucent and white. I found a dinner jacket on Amazon, then ordered it from the manufacturer’s website for about $10 less.

Okay, so I have some bad news and some good news.

"This case is empty". "What do you mean, empty?" "Empty! The opposite of full!"

In software development there is a type of defect called a heisenbug. It is named after the physicist Werner Heisenberg, who stated that the more precisely a particle’s momentum is measured, the less precisely its position can be known, and vice-versa. Likewise, a heisenbug is one which disappears when you add code or try to debug it using external tools.

When I posted about the intermittent problem with the Glowbek, I had no idea whether it was a hardware or software defect. Turns out, it was somewhere in the middle.
